I'm getting out of memory issues while using Displacement Maps. Very simple scene, DMaps are set to 2K resolution only.

I've got 2 GTX 1080s 8GB internally and an external GTX 980Ti 6GB. So there shouldn't be any memory issues. I do have the ASUS GPU Tweaker app running which lets you control all aspects of the cards (fans, clocking speed, etc.)

If I switch to CPU rendering it doesn't throw any errors, just really slow. And navigating within the main C4D window is crazy slow while I have the RTP window running. With DMaps, it really slows things down quite a bit. I don't understand why this should be an issue since I have 3 cards and the DMap resolution is only 2K. I've also got an HDRI background which is only set to 1K.

Windows 10 with latest Nvidia driver updates as well.

do you use micropoly?

Yes as I experiment more with displacement I think that seems to be the issue. I'm going to bring this up in another forum post with more details and I will share my scene file.
